All SMTP servers are showing "Offline"

Question

All SMTP servers are showing "Offline"

The Mail App on my MacBook running Ventura has suddenly stopped sending mail.

When I check the SMTP server's status they ALL show 'Offline' - Gmail, Mac Mail, Network Solutions mail?

I have not changed any of the Mail or the server settings - incoming mail via the IMAP servers are all fine.

There have been no changes on the router - iPhone and iPad Mail is working normally via Wi-Fi.

Any ideas? April 24/2023

Thanks, Bob, no I changed nothing, from one minute to the next all outoing mail smtp servers stopped working for all three different email addresses I have. I tracked it down to a OWC Thunderbolt 4 dock that stopped responding to the ethernet cable that was plugged in. I used an Ethernet to USB-C adaptor plugged into a C Thunderbolt port on the same dock and everything is working. Strange how I could receive with all accounts but not send. Anyway, the hardware problem is now solved. The other workaround was to turn on wifi. But I prefer ethernet for my needs.

Did you install a vpn?

Try booting up in safe mode as a troubleshooting step.
